Abstract: A method of forming a retreaded tire is provided. The method includes coupling a retread element to a tire casing to form a retreaded tire having a tread surface and machining a sidewall of the retreaded tire. The sidewall of the retreaded tire is then machined, where machining the sidewall of the retreaded tire includes removing a portion of the sidewall to form a concave fillet in the sidewall. The concave fillet is positioned radially inward from the tread surface.

Abstract: The present invention relates to a method for retreading tires for heavy-duty vehicles, which will find application in the transport industry and in particular in retreading the tires of various types of vehicles. The created method, in addition to the operations of the known methods of retreading, includes an operation that solves the main problem, namely: removal of residual air between the diaphragm and the tire by placing a textile tape between them. The textile strips remain between the diaphragm and the tire during its firing and thus all the air is removed due to the temperature expansions. This ensures that the diaphragm is constantly pressed over its entire surface against the inside of the tire. In addition, the problem of poor compression and adhesion of the applied patches is overcome and they are vulcanized over their entire area. When the air, which expands when heated, is removed, then it does not damage the carcass and thus it remains serviceable.

Abstract: An assembly (10) for positioning sensors within a tire is provided that has first and second bead sensors (14,16), and first and second sidewall/shoulder sensors (18, 20). A first actuator (30) moves the sensors in a radial direction of the tire, and a second actuator (32) moves the first and second bead sensors in the axial direction of the tire. A third actuator (34) is present and moves the first and second bead sensors in the axial direction relative to the first and second sidewall/shoulder sensors. A fourth actuator (36) moves the first and second bead sensors in the axial direction relative to one another, and a fifth actuator (38) moves the first and second sidewall/shoulder sensors in the axial direction relative to one another.

Abstract: Systems and methods of buffing tire casings are provided. A tire buffing machine includes a tire hub assembly selectively rotating a mounted casing, a buffer configured to buff the casing, a tire belt detection apparatus having two or more sensors to detect a first belt depth of one or more belts at a first lateral position in a tire casing and a second belt depth of the one or more belts at a second lateral position within the tire casing, and an electronic controller. The controller determines the first belt depth and the second belt depth using a belt detection apparatus having two or more sensors of the belt detection apparatus and adjusts the operation of the buffer based on the first belt depth or the second belt depth.

Abstract: A sculptured drum for a retread process that has an inner radial section with a central axis that extends in an axial direction. The sculptured drum has a plurality of support members that extend outward from a drum outer surface in a radial direction and that are located outward from the inner radial section in the radial direction. A tread that has a plurality of grooves is supported by the sculptured drum during a brushing process and pass across the sculptured drum such that some but not all of the grooves have one of the support members disposed therein. The support members when disposed within the grooves do not completely fill the grooves, and when disposed within the grooves engage a lower surface of the tread.
